Most of us believe that God is able to fulfill His promises.
However, most of what we are told is nothing more than deferred hope (Pro 13:12) - a gospel based on distance (God is far) and delay (you'd never know when, or if God would move). Pure religion!
Even the Israelites believed this lie whilst God moved visibly with them in the desert, yet instantly helped them when they were thirsty, hungry, in need of victory over their enemies, bitten by snakes, etc. etc.
